摘　　要：针对盾构机推进单级压力源液压系统在软弱不均、富含砂卵石等复杂地质环境下易受干扰,造成压力与速度波动,进而引起系统产生较大能量损失的问题,采用一种新型多级压力源液压系统,并针对复杂地质环境下传统比例积分微分(Proportional Integral Derivative,PID)控制器无法抑制外界干扰的问题设计了一种抗干扰控制器。通过分析多级压力源切换负载口独立控制系统原理,建立盾构机推进多级压力源液压系统AMEsim模型,将AMEsim模型与Matlab/Simulink抗干扰控制器模型进行联合仿真,结果表明:多级压力源液压系统结合抗干扰控制器相较于单极压力源液压系统结合传统PID控制器能更好地抑制外界干扰,将系统能量损耗减小22%左右。Aiming at the problem that the hydraulic system of shield machine propulsion unipolar pressure source is easy to be disturbed in the complex geological environment,such as weak and uneven,rich in sand and pebbles,which leads to the fluctuation of pressure and velocity,and then causes the system to produce a large energy loss.A new multi-stage pressure source hydraulic system was adopted,and an anti-interference controller was designed to solve the problem that the traditional Proportional Integral Derivative(PID)controller can not suppress the external interference in the complex geological environment.The AMESim model of the hydraulic system of shield machine propulsion multi-stage pressure source was established by analyzing the principle of the independent control system of multi-stage pressure source switching load port.The AMESim model and the Matlab/Simulink anti-interference controller model were co-simulated.The results show that:compared with the unipolar pressure source hydraulic system combined with the traditional PID controller,the multi-stage pressure source hydraulic system combined with the anti-interference controller can better suppress the external interference and reduce the energy loss of the system by about 22%.
